Application filed October 18, 1909. Serial No. 523,120.

To all whom it may concern Be it known that I, ERNEs'r O. CART- WRIGHT,a citizen of the United States, residing at Springfield, in the countyof Clark and State of Ohio, have invented certain new and usefulImprovements in Apparatus for Printing, of which the fol lowing is aspecification, reference being had therein to the accompanying drawings.

This invention relates to an apparatus for printing.

The object of the invention is to so pass a sheet or web of paperbetween the platen and form-bed of a printing press as to enable thesame to receive two or more impressions, each from a different form,either on the same or on opposite sides of the sheet or web.

A further object of the invention is to provide means for reversing thedirection of movement of the paper after it has passed once between theformbed and the platen and for laterally displacing the same and therebycausing it to pass a second time between the form-bed and platen; andfurther, to provide means for regulating the relative positions of theimpressions made by the two forms.

With these objects in view my invention consists in certain novelfeatures and in certain combinations and arrangements of partshereinafter to be described, and then more particularly pointed out inthe claims.

In the accompanying drawings, Figure 1 is a vertical, sectional view,taken longitudinally of the forward portion of a press embodying myinvention; Fig. 2 is a bottom, plan view of the turning devices; Fig. 3is an elevation of one end of said turning devices; Fig. 4 is anelevation of the other end of said turning devices; Fig. 5 is asectional view, taken on the line 00 as of Fig. 2; Fig. 6 is asectional, detail view of the adjusting mechanism; Fig. 7 is adiagrammatic view showing the paper threaded through the turning devicesin such a manner as to present the opposite sides of the same to theform-bed; Fig. 8 is a similar view showing the paper threaded throughthe turning devices to twice present the same side of the paper to theform-bed; and

Fig. 9 is a detail view of the form-bed and platen showing thearrangement of the forms and platen.

In these drawings I have illustrated one embodiment of my invention andhave shown the same as applied to a platen printing press of the typeshown and described in Patent No. 926,851, granted to me July 6, 1909,but, inasmuch as this press forms no part of the present invention, Ihave shown and described only so much of the same as is necessary to anunderstanding of the present invention and it will be understood thatthe invention is capable of application to printing presses of othertypes. As here shown, the printing press comprises a main frame 1,within which is mounted a fixed platen 2 and a reciprocating form-bed 3adapted to move in a line at right angles to the face of the platen.Mounted on the upper portion of the main frame and near the forward endthereof is a suitable feeding mechanism 41 adapted to feed the paperbetween the platen and the form-bed from a roll, which is also supportednear the forward end of the frame. This feeding mechanism is so arrangedthat the paper is threaded from the roll through the machine and isengaged by the feeding mechanism after it has received the printingimpression or impressions.

In carrying out the invention the web of paper is fed from the rollupwardly to a point near the top of the main frame of the press, aboutguides (5 and 7 and downwardly over the face of the platen near one edgethereof and in a position to receive an impression from one of the forms8, of which there are two mounted side by side on the form-bed. Whilethese forms are here shown as distinct and entirely separate one fromthe other, it will be understood that the matter to be printed by thetwo impressions may both be embodied in the same form and may be soarranged that the two portions thereof will occupy different parts ofthe form-bed. After passing between the platen and formbed and receivingthe first impression, the paper is passed downwardly to a point beneaththe platen and there passed through suitable turning devices, comprisingangle bars, as hereinafter described, which serve both to reverse thedirection of movement of the web of paper and also to laterally displacethe same. The paper then extends upwardly from the turning devices andpasses a second time between the platen and formbed near the oppositeedge of the platen and in a position to receive an impression from thesecond form carried by the form-bed. Thence it passes about the guide 6to the feeding and shearing mechanism.

The turning devices are here shown as mounted in a frame comprising sidemembers 9 and 10 rigidly secured to the lower edges of the side membersof the main frame of'the press at points beneath and slightly in frontof the platen. Mounted on the side members 9 and 10 of the frame are twoangle bars 11 and 12 arranged at an angle of 15 degrees to the face ofthe platen and extending in different directions so that their planesintersect one another at an angle of degrees. These angle bars arerigidly secured one to the other at their forward ends, where theirplanes intersect, and may, if desired, be formed from a single bar. Therear end of each bar is turned at an angle to the bar itself, and ismounted on the frame, as hereinafter described. In the present instancethe out-turned ends of the angle bars comprise the end portions of a bar13 which connects the diverging ends of the angle bars 11 and 12 andextends beyond each of said angle bars, the several bars being rigidlyconnected one to the other and preferably formed integral. A secondangle bar 14 is also supported from the frame members 9 and 10 andextends at an angle of 15 degrees to the face of the platen. This bar isarranged at a lower level than the bars 11 and 12 and has its greatestlength lying at one side of the center of the press so that it crossesthe angle bar 12 near the center thereof and at right angles thereto,and, consequently, it extends parallel with the angle bar 11. The anglebar 1st has its ends 15 and 16 turned outwardly, as shown, and supportedfrom the side members 9 and 10 of the supporting frame, as will behereinafter described. The end portion 15 of the angle bar 1 1preferably forms a part of a straight bar extending between the twoframe members and having the angle bar 1% rigidly secured thereto andpreferably formed integral therewith.

Arranged below the face of the platen and in the rear of the supportingframe for the turning devices are two guide rollers 17 and 18, theroller 18 being in a different plane and slightly in the rear of theroller 17. \Vhen it is desired that the impression by both forms shouldbe made upon the same side of the paper, the web is carried downwardlyacross the platen, under the guide roller 17, under and about the anglebar 11, thence over and beneath the angle bar 12, thence again beneaththe guide roller 17 and upwardly across the face of the platen on theside opposite the side over which it passed on its downward course. Theroller 17 is here shown as comprising two sleeves loosely mounted on thebar 13, between the ends of the angle bars 11 and 1.2, and free torotate in opposite directions to accommodate themselves to the directionof movement of the paper. The roller 18 is here shown as a sleeveloosely mounted on a shaft 28 to be hereinafter described. It will benoted that the arrangement of the guide rollers and angle bars is suchthat the same side of the paper engages each of the bars and rollers andthat the printed surface of the paper, which is the surface oppositethat shown in engagement with the rollers and bars, does not at any timecome in contact with these bars or rollers. The angle bars 11 and 12each being arranged at an angle of 45 degrees to the face of the platenserve to reverse the direction of movement of the web of paper and tolaterally displace the same so that it travels up in a path exactlyparallel with its downward path. When it is desired to print from thetwo forms on opposite sides of the paper, the web of paper is feddownwardly across the platen in a position to receive the impression ofone of the forms on one side thereof, thence about the guide roller 17,beneath and about the angle bar 11, thence laterally about a guideroller 19, which is arranged at right angles to the face of the platenand preferably in a position at one side of the supporting frame for theangle bars. The web of paper passes over and about the guide roller 19,thence under and about the angle bar 1 1, which, as above stated, islocated beneath the angle bar 12, thence rearwardly and about the upperguide roller 18, thence over the face of the platen with that surface ofthe paper which has already been printed next to the platen, therebyexposing the other side of the paper to the impression of the secondform. It will be noted that the arrangement of the angle bars androllers is such that the printed surface of the paper comes in contactonly with the last guide roller 18, and this roller being freelyrotatable, will not smear or injuriously affect the ink on said. printedsur face.

In order that the impressions received from the two forms may occupytheir proper relative positions upon the sheet or web of paper, it isnecessary that means he provided for varying the distance, 0., theamount of paper, between the two impressions. To accomplish this theangle bars are movably mounted and may be raised and lowered in such amanner as to regulate the length of paper between the two impressions onthe web. In the present instance this movement is secured by mountingthe ends 13 of the angle bars 11 and 12 in bearing blocks 20 which arejournaled in bearings 21 carried by tubular brackets 0r sleeves 22,which, in turn, are slidably mounted on vertically arranged posts 23rigidly secured at their upper ends in sockets 24 mounted near the rearof the supporting frame. The post 23 has teeth 25 formed in one edgethereof and meshing with a pinion 26 mounted in a housing 27 carried bythe tubular bracket or sleeve 22. The two pinions 26, arranged to engagethe posts 23 at the opposite ends of the supporting frame, are connectedone to the other by a rod or shaft 28 which is rigidly secured to thepinions and which causes the same to move in unison, thus causing thetwo sleeves 22 to be adjusted simultaneously and to a like extent. Theshaft 28 extends beyond one of the housings 27 and is provided withsuitable means for ro-' tating the same, such as a cross bar 29. A jamnut 30, of the construction hereinafter described, is rotatably mountedon the shaft 28 and adapted to be tightened against the adjacent pinion26 to lock the pinion and the shaft against movement, thus retaining theangle bars in their adjusted positions.

The end portions 13 of the angle bars 11 and 12 extend beyond thebearings 21 and through the apertured ends of arms or links 31, withinwhich they are secured by set screws 32. These arms or links extendforwardly and are rigidly secured to the ad jacent ends of a shaft orrod 33 by means of set screws 34. This rod is mounted in bearings 35carried by the lower ends of links 36, which links are pivotallyconnected at their upper ends to the side members 9 and 10,respectively, of the supporting frame. Thus, the rear ends of the anglebars, which are mounted on the sleeves 22, are free to move in avertical plane, the forward ends of the bars adjusting themselves tothis movement by means of the links 36. The angle bar 14 has its rearend portion 15 mounted in the same bearing block 20 as the end of theangle bar 11, thus maintaining these two bars in fixed positionsrelatively one to the other. The outer end portion 16 of the angle bar14 is slidably mounted in the lower portion of a bracket 37 and issecured in position there in by a set screw 38. This bracket issupported by that end of the rod 33 which extends beyond the arm 31 andhas a housing 38 in which is mounted a pinion 39 which meshes with theteeth 40 formed in the upper edge of the projecting portion of the shaft33. A similar bracket 41 is supported upon the end portion 13 of theangle bar 12 which extends beyond the arm 31 and has teeth 42 in itsupper edge. The bracket 41 also has a housing 43 in which is mounted apinion 44 meshing with the teeth 42 of the bar 12. The two pinions arerigidly connected one to the other by a rod or shaft 45 which has means,such as the cross bar 46, for rotating the same, and by means of whichthe two pinions are caused to rotate in unison, thus moving the brackets37 and 41 equal distances along the bars 13 and 33. A shaft 46 isjournaled at its opposite ends in brackets 37 and 41, respectively, andhas mounted thereon the guide roller 19, the position of whichrelatively to the angle bars is varied when the pinions 39 and 44 areactuated to shift the brackets 37 and 41 on their supporting members.The construction and arrangement of the shaft 45 and the pinions 39 and44 and the locking means therefor is similar to that of the shaft 28 andthe pinions 26. This locking means, as here shown, comprises a nut 47rotatably mounted on the shaft 45 and screw-threaded to engage ascrew-threaded opening 48 in the adjacent end of the housing 43, thuspermitting the inner end of the nut to engage the pinion 44 and lock thesame and the shaft 45, with which it is engaged, against rotation. Anysuitable means may be provided for actuating the jam nut 47, but, in thepresent instance, a finger 49 is secured thereto and affords a readymeans for actuating the same. By actuating the pinions and moving theguide roller 19 toward or away from the angle bars, the paper may beadjusted to cause the second impression, which, when the roller 19 is inuse, is on the opposite side of the paper from the first impression, tooccupy a proper position thereon relatively to the first impression.

The operation of the apparatus will be readily understood from theforegoing description. It will be apparent that I have devised a methodof printing, by means of which the web of paper may be fed through thepress and across the platen in such a manner as to enable two forms,both of which are mounted on the same form-bed, each to engage thepaper, the impressions on the two forms being made upon different partsof the paper and in a predetermined relation one to the other. Further,it will be apparent that I have provided a simple, easily controlledmechanism for reversing the direction of movement of and laterallydisplacing the paper to enable the method to be carried out, and thatthis mechanism is adjustable to permit the relative positions of the twoimpressions to be regulated, whether these impressions be on one side ofthe paper only or on opposite s1des the reof. In thls manner I amenabled to prlnt in two colors upon the same side of the sheet of paperor to print on both sides of the sheet of paper, both sides beingprinted in the same color or each side in a different color, the paperbeing passed through the press but once to receive both impressions.

\Vhile I have shown and described the mechanism in connection with acontinuous web of paper it will be obvious that the invention is notnecessarily confined to the use of such a web of paper. Therefore, Iwish it to be understood that I do not desire to be limited to thedetails of construction shown and described, for obvious modificat-ionswill occur to a person skilled in the art.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is
